Fuel Economy


When you turn on your TV, what do you see? Do you see advertisement by any chance? If it does happen to be an
advertisement, is it for a new model of a car? Or the improvements that the car company has made to the car? Or is currently working on improving? Towards the end of the ad you will see in big numbers, the fuel economy of the advertised car. It seems that the larger the fuel economy, the larger the numbers seem to be. What about an ad in a magazine or the paper? This is meant to catch your eye for a reason. Everyone wants to get the most that they for the least amount of money they can spend. With sky rocketing gas prices, everyone is looking for ways to save. People are more likely to buy a car with a high fuel economy rather than one with low fuel economy because they will end up saving more money. The big car companies are beginning to catch on to this. Last year, KPMG (Klynvend, Peat, Marwick, Goerdeler), one of the largest professional services in the world, a large scale survey was taken to show how many people wish that they had better fuel efficiency. Out of that survey an incredible 91% of people said that they wanted to have a car with an improved fuel economy. The competitiveness of the companies to meet demands is causing them to scrounge around frantically for new technology trying to find new solutions to this ever growing need. Many of the technologies they have been developing for years to get it right for the consumer. They keep spitting out new ideas and products claiming to improve the fuel economy and there are some incredibly beneficial products out there. One thing countless people don’t know are the simple little tune ups and changes that you can make to your vehicle to improve the fuel economy by doing it yourself and saving some of that much needed cash.

The Basics


With the economy slowly starting to get out of the rut we’re in, companies are racing to meet consumer demands and for the car companies there are numerous things they can do. The electric car is moving into the view of the public. The Ford Motor Company produced the new Ford Focus which is a definite competitor for the consumer eye in electric cars. The Focus can go up to one hundred miles before needing another charge. They can charge for six to eight hours before fully charged. For short errands this car is fabulous. It costs about half as much to charge than to run your air conditioner for a month, which could add up for some huge savings. The Ford Motor Company also has a Ford focus that runs on regular gas. This vehicle gets a whopping 40mpg (miles per gallon) on the highway and is EPA (Environmental Protection Agency) certified. The EPA inspects all of the cars that companies produce to estimate the miles per gallon the car will receive on the highway and in the city. They partner with the NHTSA (National Highway Traffic Safety Administration) to make accurate estimations. Together they test the greenhouse gas emissions and to see what other pollutants the vehicle could be emitting into the atmosphere. The car companies are trying their hardest to get their vehicles EPA certified with as many miles per gallon as they can manage. Honda has also come into the picture with their new 2012 Honda Civic HF and Hybrid Edition that matches the Ford Focus 40mpg and the highway and even just a little bit better. Honda used a lithium ion battery in the Civic Hybrid that would allow the car to reach about 45 mpg highways. The lithium ion would allow the battery to hold its energy charge much longer than a regular car battery. Holding the charge longer lets the battery stand up to a higher energy density which in turn lets the vehicle be on the road longer and let the energy be dispensed evenly over a longer period of time. Mazda has stepped up their game to play with the big boys. In 2012 they will introduce a new engine and transmission that they call SKYACTIV. This new engine and transmission provide the car with a higher value of torque that allows the car to drive easier and that result in less fuel being consumed by the engine. In 2010 the top three car companies for fuel efficient cars were Toyota, Honda and Smart Car. Toyota’s top car was their Toyota Prius with an estimated 48 miles per gallon on the highway and 45 miles per gallon in the city. Honda had their Civic in second place with 45 miles per gallon on the highway and about 40 miles per gallon in the city. The highly talked about Smart Car definitely made a statement with this little guy with 40 miles per gallon city. All of these cars make great commuters and save you a bank load at the pump. The companies sacrificed on power to get efficiency on fuel by cutting down the engines horsepower so if you want power, look elsewhere but if you want to get more mileage for your buck, then go with one of these vehicles. Big vehicles like SUVs and trucks do not get a mpg that will please the eye. The bigger the car, the harder the engine has to work to push then car so the engine uses more energy, in this case burning your gas faster than you can blink. If your car has power and speed, then you probably have a low mileage. Companies sacrifice fuel economy for speed when it comes to the expensive cars because some people prefer power over the money they could be saving on gas. When they bump up the horsepower in an engine, they force the engine to use more gas for a simple take off from a stop sign or stop light causing you to fill up more frequently and burn a hole in your pocket.

David or Goliath?


All of these companies have been using many methods such as weight reduction to also help the fuel economy of their cars. I n making smaller, lighter cars the engine does not have to work as hard to accelerate or stop the car so the engine uses less gas to power itself. Carbon fiber car parts are slowly making their appearance. These parts such as fenders and hoods are significantly lighter than the metal that is often used on these parts making the car lose some pounds. Carbon fiber is an incredibly strong but is still a lightweight material that is made of polyester, nylon and sometimes polymer. This is used to help a car get better mileage granting less work for the engine to pull. Ford is beginning to use a MuCell microcellular foam injection that is supposed to also help lighten the overall weight of the vehicle. They shoot the foam into a mold of a car body part and then let in set before assembly. This foam is lighter weight then carbon fiber but may be a little bit weaker so testing is still going on to fin specific uses for this new technology. Direct injection engines are spreading around like wildfire among the companies to use in their cars. When they use a direct injection motor, the fuel pump pressurizes the gasoline and sprays it straight into the combustion chamber where the pistons and rods are located. The atomized gasoline is combusted and ignited by the sparkplugs in the combustion chamber and this created pressure moves the pistons and rods. With the amount of pressure produced by the gasoline less gas is actually required to move the pistons and rods so you save fuel and money. The direct injection engines produce less toxins and pollution from the engine granting the engine more fuel economy. A key component in fuel efficiency is aerodynamics. Almost all of the cars you find with extraordinary mileage that is almost too good to be true, look at the size of the car. It will be a fairly small sedan or possibly smaller than that. Aerodynamic drag is one thing the car companies like to avoid because it causes more friction against the car, burning more gas at a faster rate. With smaller, sleeker cars you are more likely to have a better fuel economy because your car glides through the air with little resistance so the car does not have to work as hard to get you to where you need to go. Larger vehicles such as trucks and SUVs are not in the least bit aerodynamic because of their sheer mass. They run into the air rather and force themselves through it other than glide through it. With an aerodynamic car, your engine does not have to work as hard like it would a bigger vehicle to get you to your destination so it saves you and money gas. [5] [6]

Ethanol, Gas or both?


We hear almost every day about a new resource that they are developing for our cars to use instead of gasoline. Ethanol is one source that is stirring up quite a bit of dirt because there is much debate about if it is really a better fuel for your car. It has already been proved that gasoline with alcohol in it decreases your fuel economy because it corrodes your engine, but ethanol also has alcohol in it. So is it really all that much better? Ethanol is significantly better than gas because it does produce practically no toxins like greenhouse gases into the atmosphere and it can be produced in abundance. It is made out of grains, such as corn and wheat making it a renewable resource compared to gasoline. The fuel is made with about 10% alcohol and a bit of gasoline is added to it when it is produced. An incredibly small amount of ethanol is being produced every year because it is hard to get the amount needed to supply the people to where it needs to go. The industry for ethanol production is still a baby company but is starting to grow. Not all vehicles have engine that can use ethanol as its energy source so car companies are trying to produce vehicles that can go back and forth between gas and ethanol. Distribution of ethanol is still a problem. Gas can be pumped through pipelines across the country with ease, but ethanol cannot. The ethanol would pick up trash and impurities in the pipelines and hold on to it. These impurities would not be good for your engine because they could clog your fuel line and potentially destroy your motor. In order to be transported and distributed to the people, trucks and trains are about the only way to keep the fuel clean and get it to where it needs to go. Less toxic emissions may be a plus for ethanol but it does not mean that your car would get better fuel economy. It actually contains a substantial amount less energy than the gas you put in the car does now so more trips to the station for a fill up would be needed. The energy it takes to produce ethanol is far greater than the amount of energy the fuel actually contains, therefore we would be burning twice, even three times as much energy to produce it than it would have in itself. Genetically enhanced corn and wheat seed are in the process of being developed. These enhancements would allow the seeds to hold more energy and also produce it so when made; they would contain a greater amount of energy. You can already find ethanol in some gas stations around the country. It’s called E10 because it is actually only about 10% ethanol and 90% regular gas. This does reduce your car emissions and carbon foot print but it results in you having to fill up more often to get your destinations. If your car is a Flex-Fuel, then your engine will hold up to higher concentrations such as E85 which is 85% ethanol and 15% gas. The alcohol in the ethanol is not as corrosive to your motor as the alcohol in gas because it is burned away much slower than the gas is leaving you shape. The alcohol in gas burns quickly leaving motor in good you with less gas for an amount of time so it can skimp you on your miles per gallon. If you want to reduce your carbon footprint, fill your car up with ethanol if it allows, but you for the most out of your money, then stick with regular gas. [7] [8] [9] [10]


Did you know?

A countless number of people are under the impression that in order to improve your cars fuel economy that you just have to buy a newer and better car. This is far from the true. There are countless little things that you can do to your car that can increase you fuel economy slightly and it begins to add up to a bank load of savings. Checking your tire pressure is a good first step and you should get in the habit of doing it regularly. If the tire pressure is low then your car isn’t getting the mileage that it could be getting. When the tires are low, they flatten out and grow in width. With more of the tire on the ground, the ground will create more friction against them, resulting in the engine using more gas to push the vehicle forward. Another thing to check is the size of the vehicles tires. Big tires may make your ride look snazzy and big but whenever a car has a bigger size in tire, the harder it is to get the car going to accelerate or to turn so it burns more fuel. With a smaller tire, it is easier to get going to accelerate and its less work and energy for you motor. For those drivers that love to cut people off and drive aggressively, you are slaughtering your mileage. When you accelerate quickly from a complete stop at a stop sign or stop light, your engine starts to spray more gas into the motor making it work harder to get you there as fast as you are pushing that pedal to the ground. If you take it slowly and easily let your car start to roll after letting off the brake and gradually get up to speed limit you are saving your gas because you aren’t giving it more gas than it needs so it is burning it up faster to get rid of it in the engine. This also happens if you push the speed limit. Speed demons fill up more often than those cautious drivers because the speeders car is burning up more gas to hold you at that speed, and not to mention on top of gas prices, you will probably have to pay a speeding ticket off. You will get better mileage if you do not use your brake every second or two, because when you hit your brakes, you are making your car lose potential energy and so the motor starts to pump faster to get you back up to speed every time you hit those brakes. Not using the brakes as often also helps them to last longer, which in return will save you money as well. Use your cruise control whenever you can to save gas. Using it allows your engine to run at a lower rpm (revolutions per minute) and it does not take as much energy to keep it going when you have your foot on the gas pedal and constantly feeding the engine more gas. ====
Another way to save some green and gas is to avoid idling or stopping your car for long periods of time too often. This obviously drains away your gas and drastically decreases your miles per gallon. To help this, you could install an integrated starter generator (ISG). The ISG would shut off your motor when you came to a stop and immediately restart your motor as soon as you pushed down the accelerator. This would save gas when you are at a stop idling. Changing your air filter could also save you some green. The air filter is how the engine gets its air and cleans it. If the filter is clogged or blocked them your engine is not getting as much air as it needs to run properly. In result, your motor starts struggling to move your car because it is starving for air. Make sure you purchase an air filter that passes air through it easily. You can also check your wheel bearings to make sure that they are all greased up and easily turning with no play in the front end. By making sure that they are greased up you create less drag. With drag, your care is working against more friction to move and turn. Have your mechanic do a front end alignment to tighten up your front end and balance your wheels so they run straight and aligned. This will reduce the friction and drag of your car. You can also have your mechanic change your spark plugs. Getting new spark plugs can help you engine burn the fuel much easier and you engine will use less energy to make the plugs ignite. Clean your fuel injectors of any blockage or trash. If there is something blocking the fuel, it is keeping your motor from using the proper amount of fuel in each of the cylinders. The cylinders all need a balanced amount of fuel to run properly and if something like a piece of trash is making a cylinder get stuck open, it could potentially leak some of your precious gas. A regular oil change every three thousand miles if not a little sooner will keep you care running healthy. When your oil gets old and is not changed enough then it starts to get think and become a sort of sludge from being used so much. This oil sludge then starts to stick everywhere in your engine. It will not pass through your motor to where it needs to go very easily like it should. If the oil cannot get anywhere then the engine will start to struggle and work faster to pump the oil, in turn burning your gas. Put in oil that does not create a lot of friction in the motor. This may mean buying a more expensive brand than your usual oil but your car will pay you back with the cash you will save on gas. Use your air conditioning system less often. When you turn on your air conditioning it creates a drag on your motor because it has to now suck up more air into the care on top of what it already needs just to run properly. When you need to run some an errand, try and combine several into one trip. When you travel a short distance is a short amount of time and you do it frequently, you are burning more gas. This is because you engine stays cold and does not function as well because all of your fluids stay cold as well. Your engine needs to be warm or even hot to work like a healthy engine should so combine trips that will allow your motor to become warm so you will save on gas money. Avoid putting things on a luggage rack on the top if your car if you have one. Putting objects such as suitcases up there you are affecting your cars aerodynamics and it makes it less fuel efficient because it does not glide and push through the air like is normally would do. Also avoid putting excessively heavy things in your car. It will weigh down the car forcing your motor to push itself to work harder to go a certain speed. For more power, you could turbo charge or even supercharge your motor. When you do this, you add a fan that can circulate more compressed air to you engine and allowing more fuel to be pumped into the cylinders. With a greater amount of fuel, there is a greater power that comes from the explosions giving you a better performing car that saves you gas.
These simple tips can help you own a car with the best fuel economy it can have.[11] [12] [13] [14] [15] [16] [17] GoAnimate.com: fuel economy by alburton16
